Hello all, I have a Scrub Oak tree in my front yard, and I have St. Augustine underneath it. The grass is very thin and I was told that is because oak trees turn the soil acidic. I had lime put down last year but the grass still looks the same.ello all, I have a Scrub Oak tree in my front yard, and I have St. Augustine underneath it.

Acid peat moss makes the soil a more acidic medium for your plants to live in. It can also hold onto nutrients if the soil is dry and prone to washing out when it rains. Acid peat moss is also a fully natural way to change your soil's acidity levels and does not come with the risks that chemical modifications might.
